I made the mistake of letting my friend borrow my 8 for a date last night and when i got in it to drive today, i started the car and my traction control and abs lights were both lit up. So i immediately called my friend and was angry but he swore that he did not drive it hard. and i honestly cant even think of anything he could possible do to make both of those things cut out. the car drives perfectly fine except both of the systems do not work. I have done quite a few things to my brakes and suspension and Im wondering if a sensor could just have messed up or something. I was thinking about just resetting the ECU and see if the systems start working again. does that sound like a good idea or does anybody else have any other ideas for things to do before i start taking apart my suspension system trying to find out what is wrong. If anybody has any ideas please let me know.

Thanks
